Influence of initial structure on structure and properties of cold rolled steel quenched from alpha+ gamma- rangeN.M. Fonshtein
The paper discusses the influence of the initial parameters on the strength parameters of S235JR steel at low stress triaxiality. The analysis was performed using the Gurson-Tvergaard-Needleman (GTN) material model, which takes into consideration the material structure. The initial material porosity ...

AISI 1045 steelPitting corrosionChrono amperometryElectronic speckle pattern interferometry (ESPI)The chloride ion (Cl ) is known as an aggressive species in the aqueous solutions that adsorbs to the imperfect sites on the metal surfaces, such as defects, impurities and second-phase particles. This...
The effect of the initial microstructure of low-alloy tube steel 13KhFA on its mechanical properties after quenching from the intercritical temperature range (ICR) has been studied. It has been established that the maximum impact toughness KC V-80 is achieved in the case of the initial quenched...
Recrystallization, mechanical properties, grain size and steelThe effects of initial grain size on recrystallization and mechanical properties of steel was investigated using mild steel specimens at a different soaking temperature of 750, 850, 950 and 1050 C, respectively at holding time of 10 min ...
Mechanical propertiesFatigueAn EA4T steel billet was forged at the different initial forging temperatures (1050, 1150, and 1250 掳C). The microstructure and fatigue fracture of forged samples were observed by laser scanning confocal microscopy and scanning electron microscopy, respectively. The fatigue ...
mechanical propertiesThe present work deals with grain refinement of medium carbon steel AISI 1045 (0.45 wt.% C) having different initial ferrite-pearlite microstructure resulted from thermal and thermomechanical (TM) treatment. The purpose of prior TM steel processing was to refine grains of ferrite...
magnetic propertiesMssbauer spectroscopy, TEM, electrical resistivity and magnetic measurements are used for investigation of structural changes of X5CrNi189 austenitic stainless steel sheet induced by rf plasma nitriding carried out at 400°C for 24 h. The initial structure formed by small grains of ...
